Bronx residents are being warned about hundreds of scams aimed at stealing personal information. Identity theft was the number one consumer crime in the Bronx last year. However, there are a number of ways to keep credit information from falling into the wrong hands. Experts urge residents not to keep Social Security cards in wallets or with credit cards. They also say residents should not use birthdays when choosing personal identification numbers and never give their PIN information out. Anyone who thinks they may have been a victim of a scam or identity theft is urged to contact the Federal Trade Commission.
